    Hello Team,

    I have a Radpanelbar on a aspx and 5 items, and when clicked on item, a usercontrol is displayed in the div (that is made visible in the event OnItemClick).

    The issue that is occuring is, when I click on one item, the entire is refreshed and all the usercontrol's pageload event is fired on the page.

    I am looking at an approach where only the one user control to be loaded on click of one item instead of entire page refresh.

    Radpanel looks like:

    <telerik:RadPanelBar ID="pnlNav" runat="server" Width="180" OnItemClick="pnlNav_ItemClick"
                            EnableEmbeddedSkins="false" >
                                <telerik:RadPanelItem Text="UserControl1" Value="UserControl1" Expanded="true"
                                    PreventCollapse="true" ExpandedImageUrl="">
                                <telerik:RadPanelItem Text="UserControl2" BackColor="#608DC8" Value="UserControl2" />
                                <telerik:RadPanelItem Text="UserControl3" Value="UserControl3" />
                                <telerik:RadPanelItem Text="UserControl4" Value="UserControl4" />

     protected void pnlNav_ItemClick(object sender, RadPanelBarEventArgs e)

     switch (e.Item.Value)

                    case "UserControl1":
                        this.UserControl1.Visible = true;
                    case "UserControl2":
                        this.divUserControl1.Visible = true;
                        this.ucUserControl1.Load();//public method
                    case "UserControl3":
                      ----//same code
                    case "UserControl4":
                       same code

    Please provide any pointers if i am missing anything

    Hello PV,

    My suggestion would be to use RadAjaxManager.
    Here is a reference for it in our help documentation: http://www.telerik.com/help/aspnet-ajax/ajxajaxmanager.html
    Here is the first of many demo's in demos.telerik.com in the section for RadControls for ASP.NET AJAX: http://demos.telerik.com/aspnet-ajax/ajax/examples/manager/firstlook/defaultcs.aspx

    Hope this is going to help you!
